Risk and Uncertainty Assessment of Geothermal Projects using the Reverse Enthalpy Methodology
How do we turn complex subsurface data into confident investment decisions? Join us for an expert session featuring Roberto Gambini, a leader with nearly 40 years of experience at Enel Green Power, Shell, and ENI. We will explore the Reverse Enthalpy Methodology (REM)—an innovative approach tailored to the unique realities of geothermal development.
Key Technical Objectives
- Importance of Risk Assessment: Why robust and auditable risk assessment is essential for geothermal investment decisions.
- Lifecycle Framework: A consistent lifecycle framework for quantifying uncertainty and probability of success.
- Linking to NPV: Using the Reverse Enthalpy Methodology (REM) to link subsurface performance to NPV outcomes.
